2. Description of the Related Art In recent years, a wide variety of products have begun to appear in wide variety from popular products to low-priced watches according to various market needs. In particular, there is a strong demand for diversification of digital timepieces in which functionality is regarded as important, and there is also a strong demand for diversification in the timepiece display type timepieces.

An example will be described with reference to a schematic diagram. FIG.
FIG. 2 is a plan view of a pointer-type multifunction timepiece in which a similar structure has been conventionally provided and which is also applied to the present application. 1 is a multifunctional watch,
Reference numeral 2 denotes a case, and twelve Roman numerals I to XII for indicating the time and the month of the calendar are engraved on the circumferential portion 2a of the case 2. Reference numeral 3 denotes a dial plate, on which 60 scales indicating minutes and date numbers 1 to 31 indicating days of a calendar are engraved on a circumferential portion 3a.
29 are engraved every two scales, and 30 and 31 are engraved every one scale. Reference numeral 4 denotes an hour hand, 5 denotes a minute hand, and 6 denotes a small letter board. The small letter board 6 is provided with a second hand 7.
The hour hand 4, minute hand 5, and second hand 7 are configured to be independently driven by three motors. The hour hand 4 indicates the hour in each time function, the month in the calendar, the chronograph and the timer. The minute hand 5 displays the second for each time function, the second for the calendar, the second for the chronograph and the timer, and the second hand 7 displays the second for each time function and the second for the calendar. The age from the leap year, ON-OFF for the alarm, set time for the timer, and 1/20 second for the chronograph are displayed. Reference numeral 9 denotes a function display unit, and a time instruction unit 9
a, seven function instruction units 9a including a calendar instruction unit 9b
9g and a 0-position aligning part 9h are provided. 1
Reference numeral 0 denotes a function indicator hand, and the function indicator hand 10 is provided on the function indicator 9 by operating an external operation member described later.
The function instructing units 9a to 9g and the 0 positioning unit 9h are cyclically instructed. 15 is a push-pull button, 16, 1
Reference numerals 7 and 18 denote push buttons, each of which constitutes an external operation member for correction. The push-pull button 15 can take three positions: a normal position P1, a push-in position P2 for pushing back, and a pull-out position P3, and performs no function at the normal position P1,
By pushing back to the depressed position P2, the function indicating needle 10 is sent one step at a time, and each of the indicating units of the function display unit 9 is cyclically designated for switching. Further, by pulling out to the pull-out position P3, each function designated by the function indicator hand 10 is brought into a corrected state. The push button 17 is an external operation member for correcting the hour hand 4, the push button 18 for the minute hand 5, and the push button 16 for correcting the second hand 7 and performing a function operation in each function mode. Is pushed out in the state of being pulled out to the drawn-out position P3, thereby correcting the fast-forward of the corresponding hands.

FIG. 3 is a block diagram showing a basic configuration of the multifunction timepiece 1 shown in FIG. 20 is a microcomputer IC, 21
Is a battery, 22 is a crystal oscillator, and 23 is a switch block. The switch block 23 is a push-pull button 15, push buttons 16, 17, 18 and a function indicator 11 shown in FIG.
And the like are controlled by switches. Reference numerals 25, 26 and 27 denote three motors.
5 independently drives the hour hand 4, the motor 26 independently drives the minute hand 5, and the motor 27 independently drives the second hand 7. Reference numeral 29 denotes a buzzer which issues an alarm according to the function specified on the function display section 10.

In the pointer-type multifunction timepiece as in this conventional example, matching between the hand position information inside the microcomputer and the display of the dial and hands can be obtained by resetting the microcomputer IC 20 or jumping the needle due to impact. If not, it is necessary to adjust the reference position of the hands by input from the push button, and to match between the needle position information inside the microcomputer and the display of the dial and the hands. The method of this reference position alignment will be described with reference to the drawings. When performing the reference position adjustment, first, the push-pull button 15 is pushed back to bring the function indicating hand 10 to the position where the 0-position confirmation mode indicating unit 9h is indicated. Microcomputer IC2
A value of 0 determines the 0 position confirmation mode based on the decoded data from the switch block 23, and moves the hands of the hour hand 4, minute hand 5, and second hand 7 to the 0 position of each hand.

In the zero position confirmation mode, the user can enter the zero position correction state by pulling the push / pull button 15 to the P3 state. In the 0 position correction state, as in the other modes, the hour hand 4 can be corrected by the push button 17, the minute hand 5 can be corrected by the push button 18, and the second hand 7 can be corrected by the push button 16. The correction is one pressing and one step, and continuous correction is possible by long pressing. However,
The correction by the push button only moves the needle, and the internal information of the microcomputer IC 20 is not corrected at all.
The internal information of the hand position of the microcomputer IC20 is determined by correcting the push button to move the hour hand 4, minute hand 5, and second hand 7 to the respective 0 positions, and then push the push / pull button 15 again to change the state to the P1 state and end the correction state. This is done by:

The mechanism for determining the internal information of the needle position of the microcomputer IC 20 will be described with reference to FIG. FIG. 4 is a block diagram showing a configuration of a conventional multifunction timepiece of a pointer type. 4
Reference numerals 0, 41, and 42 denote hand position counters for the hour hand, minute hand, and second hand, which are used to store the positions of the hands on the dial. Microcomputer IC based on the value of this counter
Numeral 20 controls the movement of each hand. Reference numeral 44 denotes a hand position counter initializing means, which receives a hand position correction end signal S from the switch block 23 and sends the data to the hour hand hand position counter 40, minute hand hand position counter 41, and second hand hand position counter 42 via the data bus 45. Set a value of 0 for each. 46,4
Reference numerals 7 and 48 denote motor drivers for the hour hand, minute hand and second hand, respectively. The hour hand motor 2 is controlled by a control signal from the CPU 20a.
5. The minute hand motor 26 and the second hand motor 27 are driven.

By pressing the correction push buttons 16, 17, 18 in the 0 position correction state, the switch block 2 is pressed.
3 generates a signal (not shown) corresponding to each push button. Upon receiving this signal, the CPU 20a drives the hour hand motor 25, the minute hand motor 26, and the second hand motor 27 via the hour hand motor driver 46, the minute hand motor driver 47, and the second hand motor driver 48, and outputs the hour hand 4, the minute hand 5 The second hand 7 is moved. In the case of correcting the zero position, the hour hand 4, minute hand 5 and second hand 7 are each moved to the zero position as shown in FIG. However, CPU 20a
At this time, the values of the hour hand position counter 40, the minute hand position counter 41, and the second hand position counter 42 maintain the state before correction. After the hour hand 4, the minute hand 5 and the second hand 7 have been moved to the respective 0 positions, the push / pull button 15 is pressed again to bring it to the P1 state, and when the correction state ends, the switch block 23 generates a hand position correction end signal S. The hand position counter initialization means 44 receives the hand position correction end signal S and
The value of 0 is set to the hour hand position counter 40, the minute hand position counter 41, and the second hand position counter 42 via 5, respectively. By this series of operations, the hour hand 4 and the hour hand position counter 40, the minute hand 5 and the minute hand position counter 41, and
The second hand 7 and the second hand position counter 42 are associated for the first time.

[0009]

In the conventional reference positioning described with reference to FIG. 4, since the zero position of each hand is used as the reference position, the hour hand 4, minute hand 5,
It is necessary to move the second hand 7 to each zero position. However, in the case where the zero position on the dial is coincident with all the hands at 12 o'clock as in the conventional example, the needle that has been moved to the zero position first near the zero position at the time of correction attempts to correct it. Overlap with the needle. If the minute hand 5 is corrected to the 0 position first, the hour hand 4 and the second hand 7 are hidden by the minute hand 5 at the 0 position when the shorter hour hand 4 and the second hand 7 are corrected to the 0 position. Modification becomes extremely difficult.
Therefore, even if each of the hour hand 4, the minute hand 5 and the second hand 7 is deviated from the 0 position, the second hand 7 is first corrected to the 0 position, and then the hour hand 4 and finally the minute hand 5 are corrected to the 0 position. There is a disadvantage that the order is limited. Further, even when only the hour hand 4 needs to be corrected to the 0 position, and the minute hand 5 and the second hand 7 happen to be aligned at the 0 position and do not need to be corrected, the minute hand 5 that hinders the 0 position adjustment of the hour hand 4 is required. The hour hand 4 must be shifted from the zero position to such an extent that it does not interfere with the zero position of the hour hand 4, then the hour hand 4 must be zero-positioned and then the minute hand 5 must be zero-positioned again. That is, in some cases, the corrected needle is displaced in order to perform the zero position adjustment of one needle, and then the needle that is originally required to perform the zero position adjustment is shifted in order to perform the zero position adjustment of the needle. There is a fatal drawback that a total of two needles must be zero-aligned.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems and to provide a pointer-type multi-function capable of simpler and more accurate reference positioning without complicating a reference positioning operation and a system for realizing the reference positioning.
